16v 1995 tracker 4x4
so to get full power from the engine what is the key factors.? all misfiring causes lower engine power.
1: engine good. compression tests pass. 185psi spec, on 16v.+
2: vacuum test pass, if not the cat converter may be bad.
3: spark good, seems it misfires.
or (from bad spark, bad fuel in tank,bad compression or fuel injection rates (or fuel pressures wrong)
4: Your fuel pressure never once read correctly ever. in any post. it does not regulate. (ive no idea why only that it was wrong)
5: bad MAF.
the engine bogs for 2 season, lean fueling, (MAF? or fuel pressure low) or rich misfire, fuel pressure way to high, or leaking injectors
I think you told me all 4 spark plugs run black trips to the EFI is over injection or spark is bad, even a bad spark ignition coil bad.
in the most simple terms.
1: engine bad, (compression low or vacuum reads wrong) cam timed wrong, or CAT melted,causes crazy vacuum readings.
2: spark bad., (lots of parts there to fail) one guy replaced spark wires 3 times on the last time , upgraded to Bosch or NGK wire sets, (not $15 china crap) and engine ran perfectly.
3: bad fueling. (injectors clogged, lean, but your running rich) fuel pressure wrong, mAF bad.
just 3 causes.(mostly)
if spark is bad all the fuel in the world can not cure bad spark.
this post assumes nothing, (no parts replaced and me deleting reasons)
all we know is fuel pressure reads wrong.
